Their Right Stuff – “The Grant study has … made the bizarre discovery that subjects’ late-life mental health is strongly associated with the longevity of maternal grandfathers. That indicates a link to both traits somewhere on the X chromosome…. Just as communism, according to an old Hungarian joke, was the long road from capitalism to capitalism, psychiatry now looks like the long road that led from Darwinism to Darwinism.” – heh.

Research suggests that humans are slowly but surely losing intellectual and emotional abilities – “With the development of agriculture, came urbanization, which may have weakened the power of selection to weed out mutations leading to intellectual disabilities. Based on calculations of the frequency with which deleterious mutations appear in the human genome and the assumption that 2000 to 5000 genes are required for intellectual ability, Dr. Crabtree estimates that within 3000 years (about 120 generations) we have all sustained two or more mutations harmful to our intellectual or emotional stability.”

Culture: Diverse diagnostics – “Perhaps the most dramatic demonstration of this is a study of more than 55,000 children in South Korea, which estimated autism prevalence at 2.64%. That’s more than twice the autism prevalence in the United States estimated by the US Centers of Disease Control and Prevention, and more than 50 times higher than the South Korean government’s figure for autism prevalence of 0.046%. One reason for that higher estimate may be that the researchers screened children in the general population for autism symptoms, rather than recruiting them only from clinics for autism and other developmental disorders.”

Does cloudy weather make you ginger? – “Provisional statistics indicate that between two and six per cent of northwest Europeans are redheads, compared to an average of one or two per cent in the world population. But in the UK the numbers are much higher, with 13 per cent of Scots, 10 per cent of the Irish, and six per cent of individuals in England having read hair.”

Hacking the President’s DNA – “The U.S. government is surreptitiously collecting the DNA of world leaders, and is reportedly protecting that of Barack Obama…. In the not-too-distant future, they may provide … the basis for the creation of personalized bioweapons that could take down a president and leave no trace.”
